Circular Design Strategies and Economic Sustainability of Construction Projects in Nigeria: The Mediating Role of Organizational Culture

The need to incorporate circularity into construction is a global concern. The current linear consumption of construction materials is economically unsustainable in the midst of growing financial fears. The goal of this study is to probe the effects of circular design strategies (CDS) on the economic sustainability of construction projects (ESCP) based on the mediating role of two dimensions of organizational culture (OC). The paper observed the mediating effects of OC in the association between CDS and ESCP under the premise of the circular economy (CE) theory. The Partial Least Squares-Structural Equation Modeling (PLS-SEM) method was deployed to analyze 359 survey feedbacks obtained from Nigerian construction firms. This paper's key contribution is the confirmation of CDS's significant influence on ESCP and the partial effects of OC on ESCP in the Nigerian construction sector. Additionally, Hierarchical Culture (HC) diminishes the relationship between CDS and ESCP. This demonstrates the necessity for construction companies to create and embrace a more inventive culture—like the Development Culture (DC)—in order to promote circular practices and ultimately support the financial viability of building projects in Nigeria.
